The file is the official software image used to convert or upgrade a Cisco Aironet 2800 Series Access Point into a Cisco Mobility Express controller. This software bundle embeds an internal, software-based Wireless LAN Controller (WLC) directly onto the 802.11ac Wave 2 access point. This allows small and medium-sized businesses to deploy enterprise-grade Wi-Fi networks without the cost or complexity of a physical, hardware-based controller .
